What type of magnetic material is normally used in bubble memories?
Garnet is a type of magnetic material is normally used in bubble memories.
Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubbles or domains, each storing one bit of data.
Yttrium iron garnet (YIG) is a ferrite material with excellent magnetic and magneto-electric properties that make it the best magnetic material for high frequency applications. Thus, the magnetic moment of the garnet is a result of the surplus iron ion from d-site.
magnetic bubble. : a tiny movable magnetized cylindrical volume in a thin magnetic material that along with other like volumes can be used to represent a bit of information (as in a computer)
