Low Temperature and Strong Magnetic Field Laboratory is situated in the sub terrain floor (**room 011**) of the Department of Physics. Research is conducted using high magnetic fileds (**up to 18 T**), and low temperatures (**down to 0.3 K**). We investigate **magnetotransport properties** (resistance, magnetoresistance, Hall effect) of various materials (low dimensional conductors, oxide heterostructures,...).

Our laboratory is equiped with:

- superconducting magnets:
**18 T**and**12 T** - variable temperature inserts:
**1.5 K**to**300 K** - He
^{3}temperature insert: down to**0.3 K** - equipment for AC and DC resistance measurement: Lock-in amplifiers, AC and DC current sources (e.g. Keithley 6221), nanovoltmenters (e.g. Keithley 181)

Recent topics of our research:

**low dimensional c****onductors**We have investigated magnetotransport properties of quasi-one-dimensional conductors: Bechgaard-Fabre salts, TTF-TCNQ, quasi-one-dimensional cuprates Sr_{14-}Ca_{x}Cu_{x}_{24}O_{41}, and quasi-two-dimensional organics based on BEDT-TTF, in order to examine the influence of dimensionality on the magnetotransport properties, and to prove the importance of the correct choice of geometry for measurements of low dimensional conductors.- M.

**metallic heterostructures**We have investigated Extrinsic Inverse Spin Hall Effect in copper-iridium alloy, and we have shown that alloys combining side-jump and skew scattering are promising for eficient transformation of charge current into spin current in devices without magnetic components

**oxide heterostructures**We have investigated magnetotransport properties of oxide heterostuctures based on SrTiO_{3}(STO), which are being considered as a substitution for classical ferromagnets in spintronics. For Co-LSTO((La,Sr)Ti_{0.98}Co_{0.02}O_{3})/STO, LaAlO_{3}(LAO)/STO and ion-irradiated STO, we examined the dimensionality, the width, and the origin of the high-mobility electron layer.- G.
