Did you know?
WebSpin-on trilayer materials are increasingly being integrated in high density microfabrication that use high NA ArF lithography due to dwindling photoresist film thicknesses, lower … WebThis is preferentially a trilayer structure comprising two magnetically-soft films which are antiferromagnetically coupled via an ultrathin Ru interlayer. The functionality of this soft underlayer is to provide magnetic field flux closure for the field emanating from the recording head, thereby making the recording medium more facile to write.
WebThe need for enhanced energy storage and improved catalysts has led researchers to explore advanced functional materials for sustainable energy production and storage. … WebPEMC medium is a special type of metamaterial which generalizes the pre-existing concepts of perfect electric conductor (PEC) and perfect magnetic conductor (PMC). PEMC medium is described by a special parameter named as admittance and denoted as M. This admittance parameter acts as a base in order to extract the nature of medium as PEC or …
