Abstract: If R is a Noetherian ring and A is an Azumaya algebra over R then an ideal $ H(A)$ in R, called the closed socle of A, is defined and it is shown that $ H(A)$ is independent of the representative A in the Brauer group of R. When R is a domain, the behavior of $ H(A)$ under localization and passage to the quotient field is studied, and $ H(A)$ is calculated when R is the affine ring of a real curve.
