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.
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.
