Rare earth (RE) borides have yielded systems exhibiting interesting and varied magnetic
behaviors. The electron deficient boron atomic frameworks are a good combination with rare …

In metals, orbital motions of conduction electrons on the Fermi surface are quantized in
magnetic fields, which is manifested by quantum oscillations in electrical resistivity. This …

Strong electronic interactions in condensed-matter systems often lead to unusual quantum
phases. One such phase occurs in the Kondo insulator YbB12, the insulating state of which …

In correlated electronic systems, strong interactions and the interplay between different
degrees of freedom may give rise to anomalous charge-transport properties, which can be …

Tracking the time-dependence of a state and its observable, ie, time-resolved measurement,
is one of the ways of understanding physical principles of the system. In this Perspective, we …

Significant advances in the experimentally measuring high-field entropy have been made
over the last three decades, which have improved our knowledge of magnetic materials …

Kondo insulators are expected to transform into metals under a sufficiently strong magnetic
field. The closure of the insulating gap stems from the coupling of a magnetic field to the …

Synergic effect of electronic correlation and spin-orbit coupling is an emerging topic in
topological materials. Central to this rapidly developing area are the prototypes of strongly …

The nature of the Fermi surface observed in the recently discovered family of unconventional
insulators starting with SmB6 is a subject of intense inquiry. Here we shed light on this …

Most of the experimental results presented in this book would not have been possible to
obtain without high-quality single-crystalline samples. The history of chemical synthesis and …
