"amorphous soft magnetic composites (ASMCs) metallic powders, wrapped in coating packed with tiny air gaps and interfaces, are fast but magnetically weak... balance magnetic strength and softness by applying rotating magnetic field, creating tiny, slightly crystallized super-efficient highly magnetic regions within them... highly magnetic, flexible, high frequency magnetic and insulated coating, compaction using new techniques, highly permeable... no trade-off between saturation magnetization and coercivity/core loss"
