LCMO: Non-Magnetic at RT, Magnetic at LT

institution

At room temperature the sample shows no magnetic features. When the sample is cooled the LCMO goes through a phase transition and becomes magnetic. The sample has then reached temperatures below 250K.

LCMO, “On/Off”
The sample in the image below has been cooled to 195K. The direction of the magnetic “strips” change as the magnetic field is turned on and off.

LCMO, “Ramped Up “
The sample in the image below has been cooled to 195K. The magnetic “strip” fades as the magnetic field is turned up.
