High-pressure thermally detected electron spin resonance measurements of spin-gap compound Cu 2 (C 5 H 12 N 2 ) 2 Cl 4
Abstract
High-pressure electron spin resonance techniques offer a powerful approach for investigating the effects of pressure on magnetic materials from a microscopic perspective. Among these techniques, the thermal detection method can be combined with a split-pair-type superconducting magnet owing to its compactness, allowing for field-angle-dependent measurements. By applying this technique to the spin-gap compound Cu2(C5H12N2)2Cl4, which exhibits a marked pressure dependence, we found that the local square-pyramidal crystal field of the Cu2+ magnetic ion is deformed under pressure. This deformation suggests a significant modification of the ferromagnetic interactions within the Cu binuclear unit.
