文摘
- •
Low temperature sintered Sr-hexaferrites with La–Cu doing are successfully prepared.
- •
Magnetic properties are well explained considering the occupancy effects of La3+ and Cu2+.
- •
Electrical transport behavior follows the conduction mechanism of semiconductors.
- •
Polarization behavior obeys charge polarization mechanism of ferrite materials.
- •
The ferrite with x = 0.25 has improved physical properties for microwave LTCC applications.
