Inverting opamp amplifier: frequency response not compatible with LTspice simulation
Looks like you are using a behavioural opamp model. If so, you need to adjust the gain-bandwidth (GBW) of the model to match the GBW of the TL082 which is typically 3 MHz. Depending on the breadboard ...

Inverting opamp amplifier: frequency response not compatible with LTspice simulation
Well, notice that your transfer function is given by:
$$\mathscr{H}\left(\text{s}\right):=\frac{\displaystyle\text{V}_\text{o}\left(\text{s}\right)}{\displaystyle\text{V}_\text{i}\left(\text{s}\right)}...

Inverting opamp amplifier: frequency response not compatible with LTspice simulation
The model that you use can make a big difference in the frequency response. I don't see any number for the op-amp in the schematic, which suggests you may be using a generic op-amp model. You should ...

How to reduce gain margin to finite value?
I would prefer to call the gain margin in that plot "undefined" rather than "infinite".
When gain is measured as Vout/Vin the gain margin is defined as the factor by which you have ...

How to reduce gain margin to finite value?
The infinite gain margin becomes obvious by looking at the bode plots. The phase of the system lies between 0° and -90°, therefore the 'critical' phase of +/-180° is never reached. Speaking in terms ...
