Topic Exploring quantum magnets with magnetostriction up to ultrahigh magnetic fields
Magnetostriction is an attracting measure in quantum spin systems for local spin correlation. Exotic states such as spin nematic phase or quantum spin liquids are characterized by its abnormal spin correlations. Thus, those unusual features are generally expected to manifest themselves in magnetostriction. Recently, we have made it possible to measure magnetostriction up to ultrahigh magnetic fields [1-5], where other measures for spin correlations such as the inelastic neutron scattering are unavailable.

I will show preliminary interesting results of magnetostriction studies of antiferromagnetic quantum spin systems at high magnetic fields. In a 2D quantum spin system on a deformed Kagome lattice, volborthite, we found that spin correlation effects are visible in the magnetostriction [6]. In another 2D quantum spin system on a 1/5-depleted square lattice, CaV4O9, we followed its magnetization process up to 500 T with a spin-gap closing at 80 T and a magnetization plateau at 180-220 T [7]. In a spin-ladder system with spin-one, BIP-TENO, we found a spin-lattice decoupling phenomena, a new magnetization plateau state appears only when we use a pulsed magnetic field with a high sweep rate, that is, when the spin lattice is adiabatically decoupled from the crystal lattice [8]. Profound understanding of the schemes of the spin-lattice couplings are mandatory for understanding these phenomena.
