Non-resonant Microwave Absorption in Terbium Powders

Electron paramagnetic resonance and low-field microwave absorption in the manganese–gallium oxide

“…8. This feature suggests that other microwave absorption process sets-in, which we propose as originated by magnetic fluctuations [9,14]; i.e. fluctuations to establishment of the long-range order that precede to antiferromagnetic transition at low temperature.…”

“…This technique also allows the investigation of magnetic transitions in materials at different temperatures [8][9][10].…”

“…Additionally, the microwave absorption around zero magnetic field (low-field microwave absorption, LFMA) has been used to detect the magnetic and electric transitions in materials [8][9][10][11][12][13][14][15], and provide a high sensitive detection of the magnetic and electric orders. The origin of this signal is due to interaction of microwaves with the electric dipoles and/or magnetic moments, or also to magnetization processes which strongly depend of the magnetic order.…”
