Extreme magnetoresistance

Extreme magnetoresistance

The electronic landscape of  LaAs In his first PhD publication, Hung-Yu presented the first ever grown single crystals of LaAs. Through an elaborate analysis of magneto-transport data including resistivity and Hall effect, he searched for the origin of extreme magnetoresistance – a large and positive magnetoresistance recently observed in several topological semimetals. Two classes of explanations… Read more

Frustrated magnetism

Frustrated magnetism

Getting closer to a spin liquid state in honeycomb iridates Our postdoc, Mykola Abramchuk, succeeded to synthesize the first copper iridium binary metal oxide synthesized by a topotactic reaction from sodium iridate and copper chloride under soft conditions. Chemical analysis and crystallographic refinement reveal the composition Cu2IrO3 in a monoclinic space group with layered honeycomb… Read more

Superconductivity under pressure

Superconductivity under pressure

Superconductivity in LaBi under pressure We discover superconductivity at 3.5 GPa, XMR in LaBi. Superconductivity emerges by suppressing magnetic or charge order in correlated electron systems. However, LaBi does not have a charge or magnetic order.   At 11 GPa, it shows a structural transition concurrent with a 40% increase in the superconducting critical temperature but… Read more
