The Laboratory of extreme conditions has been formed around 2008, after successful construction of home made mini-dilution refrigerator and construction of our first diamond anvil cell. Combination of very low temperatures and high pressures allowed us to study materials under extreme conditions. Pressure is considered as clean and controlled tuning parameter of the physical properties of materials by changing inter-atomic spacing. Now we are operating several DACs and also piston-cylinder pressure cell, where it is possible to perform measurements of electrical resistivity susceptibility and magnetization.<\/p>

        3He refrigerator with AC micro-calorimetry and with Hall-probe magnetometry\u00a0<\/span><\/p>

        Two 3He refrigerators made by Oxford with 10 T (axial) and another with planar 8 T superconducting magnets. Unique AC micro-calorimeter allows to measure specific heat of microscopic samples in temperature range from 400 mK up to 300 K. Ac-calorimetry may be used in contact-less mode – thermo-couple serves as a thermometer and a sample holder at the same time and light emitting diode as a contact-less source of heat, or using Cernox chip, when the sample is attached to Cernox thermometer that serves as a thermometer and as a heater at the same time.\u00a0<\/p>

        Setup allows also transport measurements.<\/p>

        Micro Hall-probe magnetometry using array of 7 Hall probes in line, with active area 10 \u00b5m x 10 \u00b5m each, spaced by 25-35 \u00b5m allows to measure local magnetic properties.\u00a0\u00a0<\/p>

        :Scanning Hall probe microscope \u2013 SHPM is a combination of miniature Hall probes and scannning tunelling microscope (STM) from the company attocube. Sensor aproach is controlled by closed loop STM. Subsequently, local magnetisation measurements of a sample are obtained during scanning the sample underneath the Hall sensor in a close proximity of the sample surface (the distance between the sensor and the sample is few hundreds of nanometers). The movement of the sample is governed by a system of piezo-stacks which enable both coarse and fine positioning in all three directions. Scanning is possible in an area of 30×30 mm2, the coarse positioners allow displacement of 5 mm. The Hall sensor is made of semiconducting GaAs heterostructure. The space resolution of measured characteristics is limited by the dimensions of the probe. Larger Hall-probes with the side of 2 mm are available for larger magnetic structures and submicron probe with the side of 400 nm is at disposal for mapping of fine magnetic structures. The microscope is inserted in a cryomagnetic system with the 4He cryostat, VTI and superconducting magnet. The lowest operational temperature is 1.8 K and highest magnetic field available is 7 T.<\/p>

        Research\u00a0<\/p>

        The microscope enables noninvasive mapping of magnetic properties of superconductors and mangetic materials with unrivalled sensitivity. It performs local magnetisation measurements at very low temperatures and high magnetic fields. It is capable to visualize vortex distribution and pinning in pnictides, cuprates and other superconductors, to measure local field on magnetic nanoparticles, or to perform a research of bit patterned media, magnetic domains. etc.<\/p>

        The SQUID magnetometer MPMS3 from Quantum Design is located in the Laboratory. The device is designed to study the magnetic properties of solid and liquid substances, in the temperature range 1.8 K – 400 K and in magnetic fields 0 – 7 T.<\/p>

        Measurement options \/ research:<\/p>

        dc and ac measurements<\/p>

        two measuring techniques using SQUID detection: vibrating magnetometer (VSM) and DC scan<\/p>

        Shielding of the magnetic field around the apparatus (including the magnetic field of the earth) – measurement in ultra-low magnetic fields<\/p>

        Selected specifications and advantages over older types of MPMS-XL:<\/p>

        Fast sample cooling up to 30 K \/ min<\/p>

        Fast change of magnetic field up to 700 Oe \/ sec<\/p>

        QuickSwitch magnet – almost instantaneous transition of the superconducting magnet from and to a persistent state<\/p>

        Sensitivity <1×10-8 emu for H <2500 Oe<\/p>
