Magnetic Response of Conduction Electrons in Nonmagnetic YB6, LaB6, and YbB6 Hexaborides with Electronic and Structural Instabilities
A detailed investigation of contributions to the magnetization of nonmagnetic YB6, LaB6, and YbB6 hexaboride single crystals has been performed, and a procedure for their separation has been proposed. It has been shown that a low value of electronic susceptibility χe(T) in YB6 and LaB6 hexaborides seems to be associated with a small effective mass of band carriers, m* ~ 0.5m0. As a result of this, the Pauli component and Landau diamagnetism cancel each other. It has been found that χe(T) varies in the intervals T < T* (T* ~ 50 K) and T > 150 K, which are attributed to an order–disorder transition below T* and a carriers-related contribution due to the Jahn–Teller structural instability of the boron frame work.
