Magnetic materials, both hard and soft, are used extensively in several components of particle accelerators. Magnetically soft iron–nickel alloys are used as shields for the vacuum chambers of accelerator injection and extraction septa; Fe-based material is widely employed for cores of accelerator and experiment magnets; soft spinel ferrites are used in collimators to damp trapped modes; innova...

in the present work, the aa2124/25vol.%mosi2 composite was produced by powder metallurgy technique. the aluminum alloy 2124 powder was produced by gas atomization method and the mosi2 intermetallic particles were produced through combustion synthesis. the aa2124 matrix powder was mechanically blended with 25vol.%mosi2 using a ball milling mixer. the blended powder mixture was encapsulated and t...

Two types of ceramic-polymer composite thick films were deposited on Cu substrates by an aerosol deposition process, and their properties were investigated to fabricate optimized ceramic-based polymer composite thick films for application onto integrated substrates with the advantage of plasticity. When polymers with different mechanical properties, such as polyimide (PI) and poly(methyl methac...

Magnetization reversal mechanism in perpendicularly exchange-coupled composite hard/soft L10-FePt /CoCrPt bilayers with different soft layer thickness has been studied using magnetometry and magnetotransport measurements. For thin soft layers, the magnetization reversal process can be described by the rigid model. For thick soft layers, a different magnetization reversal process is observed whi...

A valveless electromagnetic (EM) micropump with a matrix-patterned magnetic polymer composite actuator membrane structure was successfully designed and fabricated. The composite membrane structure is made of polydemethylsiloxane (PDMS) that is mixed with magnetic particles and patterned in matrix blocks. The matrix magnetic composite membrane was fabricated using a soft lithography process and ...

A thorough investigation of the 2-D hysteresis processes under arbitrary excitations was carried out for a specimen innovative Fe-Si magnetic powder material. The vector experimental measurements were first performed via single disk tester (SDT) apparatus controlled induction field, taking into account circular, elliptic, and scalar processes. data relative to circular loops utilized identify m...
