Investigating the Quantum Magnetic States of K2Ni(MoO4)2

Oral-In-person

Abstract

Dimerized quantum magnets are of interest for their potential to host a Bose-Einstein Condensate of magnetic excitations (magnon BEC). While extensive research has focused on S = 1/2 dimer systems, the exploration of S = 1 dimers remains limited. In this talk, we present our investigation of the S = 1 dimerized quantum magnet K₂Ni(MoO₄)₂, a promising candidate for studying triplon and quintuplon condensation. We report on the synthesis and characterization of high-quality single crystal samples of this compound, supported by magnetic measurements. Our findings reveal exotic magnetic states at high fields, as demonstrated through magnetization plateaus. We also outline our experimental approach, including Tunnel Diode Oscillator (TDO) and magnetostriction experiments, that we used to further explore the magnetic structures at the plateau and investigate the role of anisotropy, hydrostatic pressure, and magnetoelastic coupling in this system.
