英文摘要
Phase transitions and critical phenomena near the quantum critical point of one-dimensional quantum magnets have been investigated by means of specific-heat, magnetocaloric-effect, and magnetic-torque measurements. We have determined phase diagrams of a ladder antiferromagnet and an Ising-like linear-chain antiferromagnet. In addition, we have observed release of heat from hydrogen nuclear spins driven by quantum fluctuations near the quantum critical point.
