Abstract

Motivated by a recent Electron Spin Resonance (ESR) experiment in NH4CuCl3 at room temperature, we try to propose a model for its interaction and magnetic properties. We compare this result with a recent model in other system for quantum spin-1/2 system. To clarify the ground state nature, we describe the possibility condition using schottky-type specific heat. For spin interaction we described Dzyaloshinki-Moriya interaction in anisotropy spin system NH4CuCl3.

Keywords : esr, schotthy-type specific heat, Dzyaloshinki-Moriya interaction
