Achieving Ultra-Broad Microwave Absorption Bandwidth Around Millimeter-Wave Atmospheric Window Through an Intentional Manipulation on Multi-Magnetic Resonance Behavior

Nano-Micro Letters
The frequency and intensity of multi-magnetic resonance are freely regulated by co-doping La3+ and Zr4+ ions. Zr4+ occupation is elaborately modified for promoting the portion of polarization/conduction loss to increase profoundly.
