We investigated the magnetoelastic properties of quasi-one-dimensional spin-$\frac{1}{2}$ frustrated magnet ${\mathrm{LiCuVO}}_{4}$. Longitudinal-magnetostriction experiments were performed at 1.5 K in high magnetic fields up to 60 T applied along $b$ axis, i.e., spin-chain direction. The magnetostriction data qualitatively resemble magnetization results, and saturate ${H}_{\text{sat}}\ensurema...
Elec:troactive thin-film polymers a.re increa.sinp;ly beinp; used as sensors and actuators in aerospace structures [1,2]. They also have sip;nificant potential for applications in musc:le mechanisms and micro-electro-mechanical systems (MEMS). In these applications, polymer films of thickness varyinp; between 20 and :100 tLin are utilized. Actuation of these polymers is attributed to piezoelect...
Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L_{3} absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metallic Ho after femtosecond optical excitation. Tuning the x-ray energy to the electric dipole (E1, 2p→5d) or quadrupole (E2, 2p→4f) transition allows us to selectively and independently study the spin dynamics of the...

of the angioplasty segment between the concentric and eccentric lesion subgroups was not significant (analysis of variance) at any time after PTCA. The degree of vasoconstriction observed in the angioplasty segment of both the concentric and eccentric lesion subgroups were significantly greater than that of the control segment at 15 and 30 minutes after PTCA (p CO.01 and <0.005, respectively). ...
