Direct Observation of the Ground State of a 1/3 Quantum Magnetization Plateau in SrMn sub( 3)P sub( 4)O sub( 14) Using Neutron Diffraction Measurements

We can directly investigate the ground state in magnetization-plateau fields (plateau ground state) by neutron diffraction measurements. We performed neutron diffraction measurements on the spin-5/2 trimer substance SrMn...P...O... in magnetization-plateau fields. The integrated intensities of magne...

Zusammenfassung:We can directly investigate the ground state in magnetization-plateau fields (plateau ground state) by neutron diffraction measurements. We performed neutron diffraction measurements on the spin-5/2 trimer substance SrMn...P...O... in magnetization-plateau fields. The integrated intensities of magnetic reflections calculated using an expectation value of each spin in a plateau ground state of an isolated-trimer model are in agreement with those obtained experimentally in the magnetization-plateau fields. We succeeded in the direct observation of a plateau ground state in SrMn...P...O... (ProQuest: ... denotes formulae/symbols omitted.)
