Quantum-magneto oscillations in a supramolecular Mn(II)-[3 x 3] grid

O. Waldmann, S. Carretta, P. Santini +6

The magnetic grid molecule Mn(II)-[3 x 3] has been studied by high-field torque magnetometry at 3He temperatures. At fields above 5 T, the torque vs. field curves exhibit an unprec…

Collective character of spin excitations in a system of Mn spins coupled to a two-dimensional electron gas

F. J. Teran, M. Potemski, D. K. Maude +7

We have studied the low energy spin excitations in n-type CdMnTe based dilute magnetic semiconductor quantum wells. For magnetic fields for which the energies for the excitation of…

Slow oscillations of magnetoresistance in quasi-two-dimensional metals

M. V. Kartsovnik, P. D. Grigoriev, W. Biberacher +2

Slow oscillations of the interlayer magnetoresistance observed in the layered organic metal -(BEDT-TTF)IBr are shown to originate from the slight warping of its Fermi su…

High Magnetic Field NMR Studies of LiVGeO, a quasi 1-D Spin System

P. Vonlanthen, K. B. Tanaka, Atsushi Goto +12

We report Li pulsed NMR measurements in polycrystalline and single crystal samples of the quasi one-dimensional S=1 antiferromagnet LiVGeO, whose AF transition temper…

Magnetic Field Dependent Tunneling in Glasses

P. Strehlow, M. Wohlfahrt, A. G. M. Janssen +4

We report on experiments giving evidence for quantum effects of electromagnetic flux in barium alumosilicate glass. In contrast to expectation, below 100 mK the dielectric response…

Low-Temperature Quantum Relaxation in a System of Magnetic Nanomolecules

Nikolai Prokof'ev, Philip Stamp

We argue that to explain recent resonant tunneling experiments on crystals of Mn and Fe, particularly in the low-T limit, one must invoke dynamic nuclear spin and dipola…

Dynamics in the dimerised and high field incommensurate phase of CuGeO

P. H. M. van Loosdrecht, S. Huant, G. Martinez +2

Temperature (\ K) and magnetic field (\ T) dependent far infrared absorption spectroscopy on the spin-Peierls coumpound CuGeO\ has revealed several new absorp…
