GMR Materials Types Manufactured by NVE
NVE manufactures four different types of GMR materials for use in our sensor products. These GMR
materials are described below:
Standard Multilayer (ML) – This GMR material has AF (antiferromagnet) coupling, % GMR in the
High Temperature Multilayer (HTM) – This GMR material has AF coupling, % GMR in the 8% -
Low Hysteresis High Temperature Multilayer (LHHTM) – This GMR material is AF coupled, has
Spin Valve (SV) – This GMR material has one pinned layer, has % GMR in the range of 4% - 5%,
The following table gives a brief comparison of these different GMR materials, and indicates in which
product prefix they are used:
In addition to these materials, NVE is currently developing more specialized GMR materials for
various sensor applications, including a bipolar output low hysteresis material and a spin dependent
tunneling material. Please check our web site for new product releases based on these new GMR
materials.
