AT&M CMC Cores are applied to 500KW & 1MW centralized PV inverters. High-permeability CMC Cores are applied to EMC filters near to AC output of high-power PV inverters. The better EMI suppression effect can be reached by less quantity of CMC cores due to high induction performance. Low- permeability CMC cores are applied to EMC filters near to DC output of high-power PV inverters. Low-permeability CMC cores have excellent inductance performance depend on frequency and effective anti-DC bias performance to avoid the damage from saturated inductance.

Due to the high saturation flux density of at least 1,2Tesla suitable nanocrystalline cores are the preferred solution for the tuning elements in synchrotron cavities. Related applications like particle beam de-bunchers or bunch compressors are often very much limited in space. By the use of nanocrystalline cores, the required length compared to Ferrite cores can be reduced by typically 50% - but with the disadvantage of significantly higher power consumption during operation. But due to their low impedance, the nanocrystalline cores also avoid unfavorable interactions with the ion beam and thus, they are used in several particle beam accelerator installations worldwide.
