Search for Antiferromagnetic order in ZrMn2
Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type... -
MUSR studies in the spin ferromagnetic Nd0.75Gd0.25Rh3B2 and Nd0.8Tb0.2Al2 al...
We propose to characterize the two magnetic transitions in Nd0.75Gd0.25Rh3B2 and study the spin dynamics and field induced domain rotation via zero field (ZF) and longitudinal... -
Magnetic excitations in spin ladders
We wish to measure the magnetic excitations and subgap states in a doped (x=0.06) spin ladder using MERLIN. The purpose of the measurements is to ascertain the relationship... -
