Inverse spinel structures have a different cation distribution in that all of the A cations and half of the B cations occupy octahedral sites, while the other half of the B cations occupy tetrahedral sites. An example of an inverse spinel is Fe 3 O 4, if the Fe 2+ (A 2+) ions are d 6 high-spin and the Fe 3+ (B 3+) ions are d 5 high-spin.

Hercynite is a spinel of regular symmetry and normal cation distribution, but some disorder occurs in its structure. It consists of ferrous (Fe 2+ ) ions and aluminium ions (Al 3+ ); however some ferric ions (Fe 3+ ) may be located in the structure of hercynite.
Al Michaels is probably best known to current sports fans as the voice of ABC's "Monday Night Football," NBC's "Sunday Night Football" and Prime Video's "Thursday Night Football."
Polyhedral representation of spinel MgAl 2 O 4. Spinel (/ s p ɪ ˈ n ɛ l, ˈ s p ɪ n əl / [7]) is the magnesium/aluminium member of the larger spinel group of minerals. It has the formula MgAl 2 O 4 in the cubic crystal system. Its name comes from the Latin word spinella, a diminutive form of spine, in reference to its pointed crystals. [5]
In this diagram, the red team is executing a neutral zone trap resulting in the blue team dumping the puck in. The neutral zone trap (often referred to as simply the trap) is a defensive strategy used in ice hockey to prevent an opposing team from proceeding through the neutral zone (the area between the blue lines) and to force turnovers.
Teams were allowed a forward pass in any of the zones, but the puck must be carried over a blue line by a skater. [10] Frank Boucher and Cecil Duncan introduced the centre red line in the 1943–44 season, in an effort to open up the game by reducing the number of offside infractions and create excitement with quicker counter-attacks.

In the offensive zone, the defence skaters usually "play the blue line". It is their duty to keep the puck in the offensive zone by stopping it from crossing the blue line that demarcates where the offensive zone begins. Should the puck cross this line, the offence cannot touch the puck in their opponent's zone without stopping play (see ...
