Anisotropic magnetoresistance in colossal magnetoresistive La1-xSrxMnO3 thin films
03 Sep 2010 | | Contributor(s):: Jeng-Bang (Tony) Yau
We report on magnetic field and temperature dependent measurements of the anisotropic magnetoresistance (AMR) in epitaxial La1-xSrxMnO3 (LSMO) thin flms. While in 3d ferromagnetic alloys increasing the magnetization, either by reducing the temperature or increasing the magnetic field, increases...
Anti-Reflection Coating Assignment
25 Nov 2010 | | Contributor(s):: Alex Small
This is a guided activity for students to study the design of an anti-reflection coating. The student is first asked to do a simple calculation by hand, to determine the proper thickness for an anti-reflection coating in a standard situation. The student then uses the nanoHUB tool "PhotonicsRT:...

Functional Graded Materials architectures applied at nanoscale: thin PVD nanograded and layered coatings
09 Oct 2008 | | Contributor(s):: Vasco Teixeira
Functionally graded materials (FGM’s) are designed to achieve levels of performance superior to that of homogeneous materials by combining the desirable properties of each constituent phase. FGM’s are composite materials where the composition or the microstructure is locally varied so that a...
