To study the incommensurate magnetic phase in strained (010) oriented o-LuMnO3 thin films using spherical neutron polarimetry.
We want to determine the magnetic structure of multiferroic and strained orthorhombic (o-) LuMnO3 thin films deposited on (010) oriented o-YAlO3 substrates. Recent neutron diffraction experiments on the triple axis spectrometer RITA-II, SINQ (PSI), suggests the presence of an incommensurate (IC) magnetic state at (0 qk 1) with qk~ 0.49 (r.l.u). This IC-phase persists up to TN ~38K. We will employ polarised neutron analysis using the CryoPAD set up on IN20 to resolve the intrinsic magnetic structure and determine the magnetic domain population. The sample to be measured is a 100 nm thick (010) oriented o-LuMnO3 film.
